GOOGLE_CODE has gone away.
- If a port has another upstream, remove GOOGLE_CODE
- If a port only has GOOGLE_CODE mark it BROKEN
Some ports have a local mirror configured but for security reasons, it
is not considered upstream.

Remove BROKEN, the Makefile revision which triggered the addition was
older than the revision which got the BROKEN-mark. This should build
on sparc64 (all other osversions and architectures which exhibited the
same error do not show this error anymore as of this writting).
